Y-DNA is what we call the sex chromosome “Y” that is passed from a father to his sonONLY, women do not receive a Y chromosome. Testing the Y chromosome allows for investigation into a male's paternal family line and can help identify surname lines, living relatives whose Y chromosome is similar to yours, and ancient migration routes your paternal ancestors may have taken
A DNA paternity test compares a child DNA pattern with that of the alleged father to prove or disprove their relationship with each other. We apply Polymerase Chain Reaction (PCR) V based analysis of Short Tandem Repeats (STR) of DNA fragments.
Non-Invasive Prenatal screening Test is an innovative genetic test for pregnant women at risk of foetal Patau syndrome (trisomy 13), Edwards' syndrome (trisomy 18) or Down syndrome (trisomy 21).
Checking for cancer (or for conditions that may become cancer) in people who have no symptoms is called screening.Screening can help doctors find and treat several types of cancer early. Early detection is important because when abnormal tissue or cancer is found early, it may be easier to treat. By the time symptoms appear, cancer may have begun to spread and is harder to treat.
Modern parents can now be more equipped by knowing the genetic gifts of your child. Personalized programs in school, in sports, and in all other extracurricular activities are now possible.
Thalassemia is an inherited hemolytic anemia which means the blood of its patient breaks down more frequently than normal people also they don’t have enough hemoglobin to carry oxygen which leads to the deficiency of oxygen in the body. The cause of thalassemia does not link to the loss or the intake of iron. Thalassemia is inherited, it means that at least one of your parents is either a carrier or a patient of the disease.
There are around 15 thousand people in China are thalassemia major – the most severe type of the disease. Also, around 30 million people in China are carrier. The South China i.e. Guizhou, Guangxi, Guangdong etc. is the most severe which has 1-23% among all carriers. There are around 550 thousand Hong Kong people are carrier which is 8.5% of the Hong Kong population.
Thalassemia is an inherited blood disorder, it only affects those children whose parents are carrier or patient of the disease. Thalassemia occurs when there’s a mutation or abnormality in one of the genes responsible for hemoglobin production. Children inherit this genetic defect from their parents. Thalassemia is not contagious, it will not infect others by sneezing or coughing. It means if your kids are lucky enough who did not inherit your thalassemia, you will not infect your kids by kissing them. Many people do not know they are carrier and passed their mutated gene to their children. Once thalassemia major is diagnosed, it is not curable, the patient must receive a painful life-long blood transfusion and medication treatment to prolong their life.
Hemoglobin is formed by 2 alpha globin and 2 beta globin; this 4 globin are determined by the genes inherited from parents (2 alpha globin are determined by 4 parents’ genes and 2 beta globin are determined by 2 parents’ genes). If some of these genes are mutated, the amount of globin is decreased, the symptoms and severity vary depends on this.
